Whether to preflight objects objects during Save.
In addition this also applies to the Append and AddImageDoc operations as
these involve similar concepts.
Dynamically generated PDFs can contain partially
constructed objects. At the point that two documents are combined
the partially constructed objects need to be finished in order
to ensure that the new combination is going to be valid.
For example, you add a subsetted font and some text to
a document. As you add more text, a list of characters is
built up. At the point that the document is saved, the font
object and the character list need to be combined for a sensible
font subset to be formed. This font is an example of a partially
In general if your source documents are read from existing PDF
templates then they will not contain any partially constructed
objects. It is only if the documents are corrupt or if you are
adding text, that partially constructed objects may be present.
If this property is set to true, then ABCpdf will preflight all
objects in the destination document. This process requires
significant amounts of time if the destination document
contains many indirect objects.
If the property is set to false then ABCpdf will only preflight
objects it knows to need preflighting.
